1.4 Device Information

The DAC8831 and DAC8832 are single, 16-bit, serial-input, voltage-output digital-to-analog converters (DACs) operating from a single 3V to 5V power supply. These converters provide excellent linearity (1LSB INL), low glitch, low noise, and fast settling (1.0μs to 1/2LSB of full-scale output) over the specified temperature range of –40°C to +85°C. The output is unbuffered, which reduces the power consumption and the error introduced by the buffer.

These parts feature a standard high-speed (clock up to 50MHz), 3V or 5V SPI serial interface to communicate with a DSP or microprocessor.

The devices provide bipolar output (±VREF) when working with an external buffer. The DAC8831 resets to zero code after power up. The DAC8832 resets to midscale code after power up. For optimized performance, a set of Kelvin connections to external reference and analog ground input are provided on the devices.
